Resumo: | Miltefosine (MT) is an internationally approved oral drug for the treatment of leishmaniasis, however, its mechanism of action is not yet well established. Understanding the mechanism of action of compounds with leishmanicidal activity is important to help in the search for new drug prototypes with greater activity and fewer side effects. Surfactants are compounds widely used in the industry in the manufacture of soap, shampoos and other cosmetics. They are usually classified according to the molecular charge, and may be nonionic, anionic, cationic or zwitterionic (or amphoteric) when they have a positive and negative charge in the same compound. Electron Paramagnetic Resonance (RPE) spectroscopy associated with the spin-label method was used to compare the interactions of MT and the surfactants Sodium Dodecyl Sulfate (SDS, anionic), Cetyl Trimethyl Ammonium Chloride (CTAC, cationic) and N, N-dimethyl-3-ammonio-1-propanesulfonate (HPS, zwitterionic) with the membranes of Leishmania (L.) amazonensis, erythrocyte and macrophage. All compounds increased the molecular dynamics of membrane proteins; however, SDS caused the smallest increase in parasite and erythrocyte membrane dynamics and was also the least effective in antileishmanial activity, cytotoxicity in macrophages J774.A1 and hemolytic potential in both PBS and whole blood. It was detected, in blood plasma, the albumin stiffness caused by 2.5 mM SDS due to the electrostatic and hydrophobic interactions of the compound with the protein. CTAC did not show significant differences in relation to the other compounds, but at higher cell concentrations (>1x109 cells/mL), it showed high activity against the L. amazonensis promastigotes, besides being the most cytotoxic to macrophages J774.A1. For all the experiments, the zwitterionic molecules HPS and MT did not present significant differences between them. The data suggest the possibility of using cationic or zwitterionic surfactants in formulations containing leishmanicides, aiming at the treatment of cutaneous leishmaniasis. |

Entender o mecanismo de ação de compostos com atividade leishmanicida é importante para ajudar na procura de novos protótipos de fármacos com maior atividade e menores efeitos colaterais. Surfactantes são compostos largamente utilizados pela indústria na fabricação de sabão, xampus e outros cosméticos. São geralmente classificados de acordo com a carga molecular, podendo ser não iônico, aniônico, catiônico ou zwiteriônico (ou anfótero) no caso de apresentar carga positiva e negativa no mesmo composto. A espectroscopia de Ressonância Paramagnética Eletrônica (RPE) associada ao método de marcadores de spin foi utilizada para comparar as interações da MT e dos surfactantes Dodecil Sulfato de Sódio (SDS, aniônico), Cloreto de Cetil Trimetil Amônio (CTAC, catiônico) e N,N-dimetil-3-amônio-1-propanosulfonato (HPS, zwiteriônico) com as membranas de eritrócito, Leishmania (L.) amazonensis, e macrófago. Todos os compostos aumentaram a dinâmica molecular das proteínas de membrana, no entanto, o SDS causou o menor aumento na dinâmica de membrana do eritrócito e parasita e também foi o menos efetivo na atividade antileishmania e citotoxidade nos macrófagos J774.A1. Também mostrou o menor potencial hemolítico tanto em PBS quanto no sangue integral. Em plasma sanguíneo, foi detectada rigidez na albumina causada por 2,5 mM de SDS, devido às interações eletrostáticas e hidrofóbicas do composto com a proteína. O CTAC não apresentou diferenças significativas em relação aos outros compostos, mas em concentrações celulares mais altas (>1x109 células/ml), apresentou alta atividade contra as formas promastigotas da L. amazonensis, além de ser o mais citotóxico aos macrófagos J774.A1. Para todos os experimentos realizados, as moléculas zwiteriônicas HPS e MT não apresentaram diferenças significativas entre si. Os dados sugerem a possibilidade de se usar surfactantes catiônicos ou zwitteriônicos em formulações contendo leishmanicidas, visando o tratamento da leishmaniose cutânea.Submitted by Dayane Basílio (dayanebasilio@ufg.br) on 2023-11-30T15:17:19Z workflow start=Step: editstep - action:claimaction No. of bitstreams: 2 Dissertação - Éder Jéferson Souza Cardoso - 2023.pdf: 2597358 bytes, checksum: ff4f38d5bc1aa9bcfd7139b277814fca (MD5) license_rdf: 805 bytes, checksum: 4460e5956bc1d1639be9ae6146a50347 (MD5)Step: editstep - action:editaction Approved for entry into archive by Luciana Ferreira(lucgeral@gmail.com) on 2023-11-30T15:28:38Z (GMT)Made available in DSpace on 2023-11-30T15:28:38Z (GMT).
